Tamoxifen

My 9 years old son has been taking Tamoxifen for 2 months now. He is taken care of by a wonderful team in Hadassah Hospital, Jerusalem.The drug considerably improved his condition: He can walk far longer, better and has more energy overall. And there are no side effects.

Could you share the range of CK values your son has had? I have not been able to find a range of CK values for Becker.

Thank you

Dear Galia Ben Ishay, 3-year-old son was diagnosed with BMD.47-48 exons detected deletion.Doktor said that the BMD is light but I worry too much for my son .. I have read thrilledly about your writing on temoksifen and I will have questions, 1) how much ck has fallen since using tempexifen, what was the ck value before, now how much? 2) does your son continue to improve, what changes do you observe in his or her gait and movements? 3) Do you have information about the status of other patients using tempexifene? 4) cortisone medications have periodic improvements, are you the effect of these cortisone drugs or the effect of temoksifenin? Exactly how much ck has fallen, if you write the obvious changes you observed in your son ... I wish for urgent healing and patience .. Thank you in advance for your reply ..

Galia, it is wonderful to hear that your son has stabilized! It is especially wonderful that he is retaining ability and I assume some ambulation (walking) without taking steroids. Thank you so much for sharing his progress.

I understand that your son is taking 20 mg of Tamoxifen. Could you share his age and weight? I would like to understand what his dose per kilogram ratio is.

Do you know of any other boys taking Tamoxifen without steroids?

Based on what I have read my amateur assumption is that Tamoxifen can reduce the rate of muscle breakdown which is evidenced by the decrease in CK. This has potential for slight gains in early months followed by reduced decline or stability. It is wonderful that your son's experience is consistent.

As for availability, Tamoxifen is available for other conditions in the US. It is primarily used to treat breast cancer but has also been used to treat male teenagers with excess estrogen. I understand that it could be obtained via an off label prescription from a willing doctor. I am not aware of any use for Duchenne treatment in the US. A clinical trial is starting in Europe. I would encourage those within reach to participate in that trial.

I was wondering if your son is still using tamoxifen and if the situation is still stable or better. Is your son also using prednisolone or Deflazacort? And are there any side effects with tamoxifen? Can you also tell me when your son is start using tamoxifen?
